Abstract (en)

An electric impact tightening tool in which the rotation of an output section of an electric motor is transmitted to an impact generation section and an impact force generated in the impact generation section causes a strong torque to a main shaft, and the electric motor is an outer-rotor electric motor. This outer-rotor electric motor has low-speed and high-torque characteristics. The impact generation section and a rotor flange at a forward end of the outer-rotor electric motor rotate together simultaneously as if they were one body. The electric impact tightening tool which is small sized and lightweight, and has a low reaction force and durability is provided.
